This comprehensive craft on online marketplace development will guide you through everything you need to know when building your own multi-vendor marketplace, including what a marketplace is, its types, revenue streams, key features, steps to build, the development approach and much more. 

However, before we delve into the blog, let’s take a look at the revenue the eCommerce industry generated and the expected growth in the upcoming years. 

The global retail eCommerce market size in 2025 hit $21.62 trillion and projections indicate it will surpass $75.12 trillion by 2034, growing at a CAGR of 14.88%, according to Precedence Research.

What is an Online Marketplace?

An online marketplace is a digital space that connects buyers and sellers. It works as an intermediary between buyers and sellers. Multiple sellers list and sell their products on the marketplace. Buyers also get access to a wide range of products from different categories. 

On the one hand, sellers can list their products, providing all the necessary information, including images and other graphics. On the other hand, buyers search and browse products and proceed to checkout if they find the product useful. 

The admin is another participant on the online marketplace who takes care of the operational aspects. They ensure that the platform operates seamlessly without any disruption. Moreover, the admin, the online marketplace operator, generates revenue from multiple sources without the need for inventory.

All activities and transactions take place electronically on the online platform. The marketplace users simply need a device connected to the internet that can help them browse and perform tasks as per their specific roles.  

What are the Different Types of Online Marketplaces?

Online marketplaces target a diversified group of buyers and sellers. They all connect with their unique needs and initiate transactions differently. Hence, the marketplace required distinct features and functionalities to ensure seamless transactions. Therefore, online marketplaces are built differently and are of different types. 

Below are a few popular marketplace types entrepreneurs and business owners should explore before building their marketplace. This will help them understand how marketplaces work and which type of marketplace best suits their idea. 

• Business-to-Consumer (B2C) Marketplace

As the name suggests, a B2C marketplace connects businesses directly with customers. Businesses (Sellers) list their products and customers can search for and buy them on the platform based on their specific requirements and personal interests.

Examples: Amazon, eBay, Walmart  

• Business-to-Business (B2B) Marketplace

Unlike B2C, where businesses sell products to customers, B2B marketplaces enable trade between businesses. One acts as a vendor and the other as a customer. Compared to B2C, B2B marketplaces handle large-volume orders and are primarily built for manufacturers, wholesalers, and suppliers.  

Examples: Alibaba, Amazon Business, Global Sources 

• Customer-to-Customer (C2C) Marketplace

This type of marketplace operates uniquely. Rather than enabling trade for businesses, these platforms connect two individuals based on their personal interests. In short, C2C marketplaces operate vice versa, where both individuals can buy or sell products. 

Examples: Etsy, Poshmark, eBay 

• Product-based Marketplace

This type of marketplace only sells products online. However, the products sold on the platform can either be physical or digital. In short, product-based marketplaces offer products of all types, including new or old and manage shipping to ensure delivery at the doorstep. 

Examples: Amazon, Alibaba and Etsy 

• Service-Based Marketplace

Rather than selling products, a service-based marketplace offers services. This type of platform enables businesses or individuals to provide or book services online. Primarily, there are two different types of participants operating on the platform: first, those who offer services and second, those who avail these services. 

Examples: Airbnb, Uber, Upwork

• Horizontal Marketplace

Horizontal marketplaces focus on selling products across diverse industries and categories, catering to the needs of a wide customer base. This type of platform is considered a one-stop shop that almost fulfills all the requirements of the target users. 

Examples: Amazon, Alibaba, Walmart

• Vertical Marketplace 

Vertical marketplaces are specialized platforms that focus on the specific needs of customers. Unlike Horizontal marketplaces, they cater to customers looking for products from particular segments and categories. Vertical marketplaces bring specialized niche-based solutions to their targeted customers, which makes the marketplace distinct and helps them build a trusted customer base. 

Examples: Etsy, Poshmark, Chewy 

Revenue Model: How Does an Online Marketplace Make Money?

Revenue generation is the ultimate goal of any business. No matter whether operating online or offline. To run and sustain your business, you need to decide on the monetization model.

However, when operating an online marketplace, you can generate revenue from multiple streams. Below are a few popular revenue streams marketplaces use to make money from. Let’s explore them and learn how to make money on an online marketplace. 

1. Commission: Commission is one of the most preferred monetization models that marketplaces often choose. A certain percentage or a fixed amount is charged as commission. Marketplaces can charge commission on each sale or transaction that takes place on the platform. Mostly, commission is charged by the vendor. 

However, charging commission from customers can also be a revenue-generating strategy. Etsy, Vinted and Airbnb are examples of marketplaces that charge commission from customers. Buyers are also charged commissions on successful payments. 

2. Subscription Fees: Marketplaces generate a steady income from monthly, quarterly or yearly subscription fees. A subscription is a kind of membership fee that brings additional value to the subscribers.

Users, including vendors and customers, pay a recurring fee to gain access to the premium services, such as access to the content, prior access and updates on sales, and access to the premium tools, free shipping options and much more. 

3. Listing Fees: Marketplaces charge a fee from sellers to list their products. However, the charges can vary depending on the product value or monetization strategy. This model enables marketplaces to generate revenue from the very beginning and also attract quality listings.

At the same time, it can limit the number of listings due to listing fees that ultimately affect the marketplace’s growth. Therefore, marketplaces implementing these revenue streams should keep an eye on the targeted market and then decide on the revenue model accordingly.

4. Featured Listings: Marketplace allows sellers on the platform to promote their products either individually or in multiple. In this monetization model, sellers pay charges to promote their listings. Marketplace, in return, increases the visibility of its products or listings in search results or on the marketplace. 

5. Third-party Advertisement: It’s a well-known revenue model that marketplaces make money from. Third-party advertisers rent out ad space on the marketplace if they find the marketplace users useful to them. They promote their businesses via banners, graphics or text, paying charges to the platform.

However, enabling third-party advertisements on the marketplace may lead to a bad customer experience and cause loss. Sometimes, unwanted ads and promotional activities frustrate customers.

Must-Have Features of an eCommerce Multi-Vendor Marketplace

Marketplace requires the necessary features and functionalities to be operational. However, features and functionality can vary depending on the marketplace type, operations and specific needs. Nevertheless, given user-wise features below are critical, which may work for most of the marketplaces. 

Buyer-specific Features

• User Registration: Buyer’s first interaction on the marketplace begins with user registration. This process includes validating contact and personal details required. However, marketplaces also allow customers to interact without registration initially and later take all the necessary details during checkout. 

• Advanced Search and Filter: After registration, search is another important feature required for the buyer’s buying journey. Using this feature, buyers search and find the products that they look for. In addition to search, the filter option enables buyers to get more accurate and precise search results. 

• Add to Cart: Using this feature, buyers can add products to their virtual shopping cart. Later, they may either view the products or proceed to checkout based on their preferences. 

• Multiple Payment Options: Multiple payment options give buyers flexibility to make payments using their preferred option. At the same time, a marketplace that integrates with multiple gateways also builds trust among buyers.  

• Easy Checkout: Easy checkout is an important feature on the platform that enables buyers to make purchases effortlessly. One-click checkout is trending these days. However, a significant percentage of buyers left without completing the checkout due to the complex process and multiple steps.

• Order Tracking: It’s another important feature on the marketplace. Using this feature, buyers track orders and get updates on their current statuses. Alongside providing order updates, this feature also contributes to reducing the chances of order returns. 

• Customer Support: Effective customer support can make all the difference. It helps the marketplace build a loyal customer base enhancing overall customer experience. Often, marketplaces fail to provide resolutions on the right that cause users to migrate. 

• Ratings and Reviews: Ratings and reviews play an important role in building trust among customers. Using these features, customers give ratings and reviews of the products or services based on their experiences, which also helps buyers in making decisions. 

Vendor-Specific Features

• Vendor Registration: Similar to buyers, vendors also need to register on the platform. An easy vendor registration process helps in improving the first interaction of the seller on the platform. However, the process can be different. They need to provide information and details specifically to their business rather than just individual details. 

• Product Management: This feature allows vendors to manage their products on the platform. Starting from listing products to updating pricing, uploading images and other product-related information.

• Inventory Management: Using this feature, sellers keep track of the inventory. They can manage and control stock. This feature provides real-time updates on Sellers’ current stocks at different levels and lets them avoid stockouts or overstocking.

• Order Management: Once the order is placed, the order management feature on the marketplace enables sellers to process and fulfill it. It streamlines and automates the entire order lifecycle. Not only helps ensure delivery at doorsteps, but manages returns. 

• Coupons and Discounts: Using this feature seller can give discounts or create a unique code that the buyer can apply to avail the discount. This feature primarily helps sellers attract more buyers and increase the number of sales on the marketplace. 

• Analytics and Reporting: The Analytics and reporting feature for sellers on the marketplace provides valuable data and insights. They can check sales reports, listing performance, best-selling products, regions where products are performing well, the age group they target and much more. Using this valuable data and insight, they can further plan their strategies and generate more sales.

• Ads and Promotion: Using the ads and promotion feature or tool, sellers increase the visibility of their products. They boost their products on the marketplace via paid ads beyond organic and generate more sales by reaching potential buyers.  

Admin-Specific Features

• Content Management: CMS (Content Management System) enables the marketplace admin to manage digital content on the marketplace. They can even change look and feel, tailor some functionality and more using the content management system without the need for coding expertise. 

• User Management: The marketplace admin needs to manage users and their roles. User management features can approve or reject sellers and manage other users, including assigning sub-admins. 

• Revenue (Commission) Management: This feature allows the marketplace administrator to decide and define the revenue model. They can set their commissions, subscription fees, modify plans and other associated charges using this feature. 

• Analytics and Reporting: Similar to sellers, the marketplace administrator has access to valuable data and insights using the analytics and reporting features. However, the data they need is different from the data sellers require. 
  They can get an overview of the overall marketplace performance, customer behavior, sales trends and more. These insights help them make an informed decision and allow them to grow their platform and achieve goals. 
• SEO and Marketing: If you want to stand ahead in today’s competitive market, all you need is proper planning and the right tools to execute it. SEO and marketing features are also one of those tools that help marketplaces beat their competitors, reach their targeted customer base, promote their marketplace and build a brand.  
  On the one hand, SEO helps in improving organic reach. On the other hand, integration with paid marketing tools allows the marketplace to reach potential customers. 
• Tax Management: Tax management tools automate tax management, allowing admins to manage tax effortlessly. They calculate the tax rate for each transaction initiated depending on the region, current tax law, product type and more. Tax management tools also help admins manage cross-border tax by simplifying overall tax management.

In addition, it’s crucial to properly plan strategies to onboard the maximum number of vendors, listings, attract more customers and more.
